Did you check oracle memory settings? Can it be Oracle is just configured wrongly? Would not be the first time - my last project had a 2x96gb RAC configured to use 8gb memory only ;) –  TomTom Jun 4 '12 at 6:06

Standby Memory-- is memory that has been removed from a process's working set (its physical memory) en route to disk but is still available to be recalled.

or in other word

Standby Memory -- Memory that contains cached data and code that is not actively in use
